Formula

Formula
kg/s = g/hr × 2.777778e-7

Multiply any value in grams per hour by 2.777778e-7 to obtain the value in kilograms per second.

Worked example

Convert 1.00000e+6 g/hr to kg/s.

  1. 01Start with 1.00000e+6 g/hr.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 2.777778e-7 = 0.277778 kg/s.
Result1.00000e+6 g/hr = 0.277778 kg/s

FAQ

What is the conversion factor from g/hr to kg/s?
1 g/hr equals 2.777778e-7 kg/s. To convert, multiply the value in grams per hour by 2.777778e-7.
How do I convert 1 g/hr to kg/s?
1 g/hr = 2.77778e-7 kg/s. For any value, multiply by 2.777778e-7.
How do I convert kg/s back to g/hr?
Divide by the same factor — or equivalently, multiply by 3600000. So 1 kg/s = 3.60000e+6 g/hr.
When would I need to convert gram per hour to kilogram per second?
Mass flow conversions between g/hr and kg/s are common in material balances, process stream summaries, bulk solids handling, custody transfer, and equipment sizing where kg/hr, t/hr, lb/hr, and lb/s may all appear in different datasheets or vendor documents.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
